Design of light-controlled automatic tracking solar street lamp

Abstract

Disclosed is a light-controlled automatic tracking solar street lamp. The light-controller automatic tracking solar street lamp comprises a solar battery panel (1), a motor (2), a shading baffle (3), an LED (light emitting diode) lamp (4), a central controller (5), a photosensitive sensor (6), a storage battery pack (7) and a lamp post (8), wherein the photosensitive sensor (6) can automatically sense the light intensity of external environment and transmit signals to the central controller (5), the central controller (5) automatically adjusts the light intensity of the LED lamp (4) according to current brightness, so that the problem of energy waste and service life shortening of street lamps under long-time high-brightness high-power working conditions can be solved. At daytime, the central controller (5) can automatically adjust the angle of the solar battery panel (1) through the motor (2) according to the track of the sun during the day to convert more solar energy into electric energy for storage in the storage battery pack (7), so the night lighting electricity consumption can be achieved without assistance of common power sources, and further green and environmental protection can be obtained.

Description

technical field [0001] The invention relates to a solar street lamp, especially an LED street lamp with automatic brightness adjustment according to ambient light and darkness, and which can absorb light energy to the greatest extent as a power source by adjusting the angle of a solar battery panel. Background technique [0002] Most of the street lights currently in use use ordinary power sources and ordinary light bulbs. There have also been street lights that convert solar energy into electrical energy to power street lights, and street lights that can automatically adjust brightness according to the ambient light. However, due to the large power consumption of ordinary light bulbs, it takes Mains auxiliary power supply does not achieve the optimal energy-saving effect, and the street lamps are likely to waste energy and shorten the service life of street lamps due to long-term work in high-brightness and high-power conditions. In addition, the solar panels of current sol...

AI Technical Summary

Problems solved by technology

[0004] Another object of the present invention is to provide a photosensitive sensor that automatically senses the brightness of the external environment and sends a signal to the central controller. In the case of high brightness and high power, it will cause waste of energy and the service life of street lights
